Abstract
The utility model relates to a blood-taking holding tube for the clinical examination, which comprises a needle tube (2) and a built-in pintle handle (1) as well as a piston (3), wherein the top end of the needle tube (2) is provided with a tube head (4), a needle head (5) and a needle cap (6), and the base part of the needle tube (4), i.e. the position which is connected with the needle tube (2), is provided with a needle tube switch (7). The blood-taking holding tube for clinical examination reduces the operation links and can effectively prevent the cross infection and the hemolysis phenomenon. The blood-taking holding tube for clinical examination can take the blood correctly and is free from causing waste or insufficiency.
Description
Technical field
This utility model relates to a kind of Clinical Laboratory medical apparatus, is specifically related to the blood sampling that a kind of Clinical Laboratory uses and holds pipe.
Background technology
During existing blood test, the hemostix that is adopted is a disposable syringe, holds the disposable test tube that is of blood, then the blood injecting tube is held with blood collection needle during blood sampling, carries out blood test then.This blood sampling holds mode cross infection, haemolysis takes place easily, and operation of medical workers is also cumbersome.
Notification number: CN201073308, the Chinese patent literature of the day for announcing: 2008.06.18 has been announced " blood taking tube that a kind of Clinical Laboratory is used ", this blood taking tube comprises syringe, test tube, test tube plug, needle stand, outer syringe needle, interior syringe needle, described syringe front end is a needle stand, the outer syringe needle that communicates, interior syringe needle are housed on the described needle stand, described back end of syringe is a handle, described test tube one end is sealing, opening is provided with a test tube plug, described is negative pressure before use in vitro, and described test tube can slide in syringe.Test tube is the Sheng blood vessel, has become the piston rod of ordinary syringe again, once finishes blood sampling, annotates two processes of blood, has prevented in cross infection and the operating process the pollution of blood sample, and is simultaneously, simple in structure, easy to use.But this utility model because difference, adds that formed negative pressure pressure is difficult to control by blood sampling person's body situation difference, often makes blood sampling volume not enough or too much in actual use, brings a lot of inconvenience to the patient.
Summary of the invention
The purpose of this utility model is deficiencies such as, operational stability difference many at existing hemostix operation link, provides the blood sampling that a kind of operation link is few, a kind of Clinical Laboratory of good stability is used to hold pipe.
The purpose of this utility model realizes by following technological means: the blood sampling that a kind of Clinical Laboratory is used holds pipe, include needle tubing and built-in pintle handle, piston, the top of needle tubing is provided with tube head and syringe needle, pin medicated cap, the base portion of described tube head, promptly the position that is connected with needle tubing is provided with the needle tubing switch.
Described needle tubing wall is provided with scale.
The upper end oral area of described needle tubing is provided with Yi Jianzui.
The base portion of described needle tubing is provided with a pedestal.
Compared with prior art the utlity model has following tangible advantage: 1, the blood sampling used of this Clinical Laboratory holds pipe and can reduce operation link, can effectively avoid cross infection and haemolysis.2, the blood sampling used of this Clinical Laboratory holds pipe and can take a blood sample accurately, can not cause waste or not enough situation.3, the blood sampling used of this Clinical Laboratory holds the control blood drawing that pipe can be stable, and the erratic situation of other amount can not take place.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1, the pintle handle, 2, needle tubing, 3, piston, 4, tube head, 5, syringe needle, 6, the pin medicated cap, 7, the needle tubing switch, 8, scale.
The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment this utility model is described in further detail:
The blood sampling that a kind of Clinical Laboratory is as shown in Figure 1 used holds pipe, include needle tubing 2 and built-in pintle handle 1, piston 3, the top of needle tubing 2 is provided with tube head 4 and syringe needle 5, pin medicated cap 6, the base portion of described tube head 4, and promptly the position that is connected with needle tubing 2 is provided with needle tubing switch 7.Described needle tubing 2 walls are provided with scale 8.The upper end oral area of described needle tubing 2 is provided with Yi Jianzui.The base portion of described needle tubing 2 is provided with a pedestal.
Be provided with like this, when the blood sampling of using this Clinical Laboratory to use holds pipe and takes a blood sample, take off pin medicated cap 6, open back needle tubing switch 7, slowly twitch pintle handle 1 drive piston 3 and finish blood drawing, be provided with scale 8 according to needle tubing 2 walls and monitor what of blood drawing amount constantly, so just can take a blood sample accurately, can not cause and waste or not enough situation.After blood sampling finishes, needle tubing switch 7 cuts out, pull out tube head 4 and syringe needle 5, at this moment, the blood that the blood sampling that this Clinical Laboratory is used is gathered in holding and managing just can be used as test tube and be placed on the test tube rack, uses for check.
In a word, the blood sampling that this Clinical Laboratory is used holds pipe can reduce operation link, can effectively avoid cross infection and haemolysis.The blood sampling that this Clinical Laboratory is used holds the control blood drawing that pipe can be stable, and the erratic situation of other amount can not take place.
